Hi @kcasper,
When you create an item in the SharePoint list, the input data type should match the corresponding column type. Such as the Currency field should input value which is number format, Person field should be email format.
And some values from the Excel table will have some changes when it extracts from excel, you should process them individually before appending them.
Could you please share an instance of the item from Excel? (Please shield key information)
